site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Apple has its own static analyzer from the LLVM project. CLANG: http://clang.llvm.org/StaticAnalysisUsage.html Works pretty well on the few apps I've run it on.

It seems that Apple is not interested in porting this application and it is also difficult to port by the valgrind team. Is there any sensible alternative to find memory leak, or memory corruptions, etc for console applications? Instruments and Shark do not fit properly for this purpose.
